Police are asking for the public's help in finding whoever duct-taped a dog's mouth shut and left him stranded on the side of a Long Island, New York, highway.

Authorities on Long Island are offering a $2,000 reward in a case involving a German shepherd found with its muzzle taped shut.Suffolk County SPCA

The 2- or 3-year-old German shepherd was found Saturday on Montauk Highway in Lindenhurst, authorities said.

Roy Gross, chief of the Suffolk County SPCA, told NBC News that the dog "didn't seem to be in this condition for long, so we believe this is something that happened last night or sometime late yesterday."
